A basic Euler equation fits poorly, but habits and recursive preferences can improve fit. Where is the same empirical discipline for Post-Keynesian/SFC models? Do they even match basic moments? Without even basic statistical tests, how can SFC models be taken seriously?

J'ai demandé à Opus de faire un résumé de cette affaire sur la base de diverses sources, dont la petite partie qui y est consacrée dans mon livre de janvier prochain.

🚨 Job Market Paper
❓ Dispersion in firms’ capital intensity has widened. Why, and does it matter?
⚙️ Firms unevenly update the capital-intensity of their technology as capital goods get cheaper.
📊 This helps explain major US trends.

I’m on the job market this year! 🥳
My paper studies who benefits from capital market integration in a monetary union facing asymmetric shocks.

Food for thought!
"Monetary Policy in the Euro Area, when Phillips Curves ... are Curves" by Guido Ascari, Alexandre Carrier, Emanuel Gasteiger, Alex Grimaud, and Gauthier Vermandel.
"We study monetary policy where the price and wage Phillips curves exhibit true curvature. To this end, we propose a New Keynesian (NK) model featuring endogenous adjustment of price and wage setting frequencies, moving beyond the quasi-linear structure of the standard nonlinear NK Phillips curves (NKPC)."
"Unlike conventional models, our framework does not primarily explain inflation dynamics by exogenous supply shocks. Instead, the impact of shocks on inflation depends on their timing, size, and the business cycle. Consequently, the inflation-output stabilization trade-off faced by monetary policy is state-dependent."
cepr.org/publications/dp2048…
New paper: we estimate a fully nonlinear New Keynesian model for the Euro Area, where Phillips curves have true curvature from endogenous price adjustments. Recent inflation dynamics strongly depend on economic conditions, creating state-dependent trade-offs for monetary policy!

En tant qu’ambassadeur aux États Unis, je n’ai cessé d?y rencontrer des chercheurs français qui auraient préféré revenir dans leur pays mais qui se heurtaient aux conditions qu’on leur y offrait en termes de rémunération et de laboratoire. Ce genre de déclaration m’effare.
La France peut accueillir « des centaines de chercheurs » du monde, juge le ministre de la Recherche
